ATTACHMENT FOR FILLING GREASE-CUPS.

Specification of Letters Patent.

Patented May 128', 1912.

Application filed June 14, 1910. Serial No. 566,872.

To all whom it may concern Be itknown that I, MATTHIAS GEORGE BROWN, a citizen of the United States, residing at Gulfport, in the county of Harrison and State of Mississippi, have invented certain new and useful Improvements in Attachments for Filling Grease-Cups, of which the following is a specification, reference being had therein to the accompanying drawmg.

The invention comprehends a portable receptacle adapted to carry a quantity or supply of lubricant provided with means for removably attaching the same to a grease cup and instrumentalities for" discharging the desired amount of the lubricant from said'receptacle into the cup.

As will appear to those skilled in the art, the invention also embraces the formation of a filling device of the general character referred to with a coupling element adapted to cooperate with a complementary element formed on a part of the grease cup structure facilitating a quick connection or disconnection of the filling device relative to the said cup.

A convenient embodiment of the invention includes a grease cup formed with a seat communicating with a fill opening, a filling device having a part to correspond with said' seat and register with said fill opening, anda separable coupling intermediate of the filling device and the cup to temporarily retain Preferably, also, the above stated embodiment of the invention comprises for the coupling means cooperating separated flanges or lugs having opposing inclined faces to create a binding action therebetween upon a relative turning of the parts, the arrangement being such that what Imay term a quick engagement or release is afforded.

involving simply a quarter-turn of the one member relative to the other.

The foregoing characteristics of the invention, and the details in the construction and arrangement of the parts will be a parent from the specific description hereinaf ter contained when read in connection with the accompanying drawings forming part hereof and wherein the convenient embodiment of the invention to which I have above alluded is illustrated.

In the drawings, Figure 1 is an elevation of one end of a machine element, for instance, an engine pitman, having the usual grease cup provided with my present improvements and the filling device attached.

thereto, Fig. 2 is an elevation of the filling device detached, Fig. 3 is a vertical longitudinal section through Fig. 1,Figs. 4, 5, and 6am detail views showing the coupling devlces.

Referring more specifically to the drawings, wherein like reference characters designate corresponding parts in the several views, A represents one end of an ordinary pitman, B the pin upon which the same is pivoted and which latter it is desirable to maintain in a lubricated condition, and O is the usual grease cup formed integral with the pitman opening throu in the base thereof to the pivot pin B.

D is the cover for the oil cup having an internal threaded engagement d with the mouth of the cup and a wrench-hold J as usual. As distinguished from the cap or cover customarily employed, the cover D in this instance is provided with an upwardly projecting centrally disposed stem (2 having an aperture 6 communicating with the hol low interior (1 of the cover C and arranged at the baseof an inwardly tapering seat E at the mouth of said stem. At the upper end of thestem cl and formed integrally therewith, 95 pair of separated lugs or flanges f are arranged to project laterally from the stem and overhang the top F of the cap D with spaces f therebetween, said lugs or flanges being beveled or inclined on their under surfaces, and the separation thereof being for the purpose of providing'what I may term entrance passages f for similar lugs or flanges on the lubricant receptacle now to be described,

As will be apparent, the lubricant receptacle, represented at G may be of any desired size and shape, and the same may be provided with any preferred or suitable discharging means, that shown consisting of a hollow plunger or piston H having a threaded engagement g with the topof the .receptacle, the upper end of the piston or plunger It being of angular formation to facilitate the adjustment thereof. The interior of the lower portion of the receptacle inclines to a discharge outlet 2' in the base I of the receptacle, a tapered nipple J being provided at this point to fit the seat E in the cap of the grease cup heretofore referred to.

K are flanges spaced apart asat k, and

adjoining the base of the receptacle -pro-* jecting inwardly from the lower edge of a tubular extension is, of the receptacle G,

extending a suitable distancebelow the nipple J to provide a space 70 therebetween.

:These flanges are also tapered, providing.

beveled or inclined upper surfaces and are adapted to be slipped through the entering openings on the cap and byapproximately a quarter-turn of the receptacle brought into impingement with the correspondingly tapered lugs or flanges f on the cap to create a wedging action between the lugs and a binding engagement between the nipple J and its seat E.

same to attach or detach the cap. a

From the foregoing disclosure, it will be appreciated that by the use of a construction; in keeping with my invention, grease cups may be filled in an expeditious and the receptacle from cleanly manner, it being simply necessary to couple the attachment constituting the grease gun or dispensing vessel to the cup An angular surface 9 on the receptacle facilitates the turning of the and arrangement of the expelling plunger may be changed, for instance, to provide an externally arranged hollow cap engaging the receptacle; and the cooperating beveled lug-coupling; idea may be the reverse from that shown, that is with the cap of the lubricant cup formed hollow with the internal lugs and the supply receptacle formed with the external lugs.

In a lubricating apparatus, the combination of a lubricant-receiving member mounted in fixed position on the article to be lubricated, a cover for said member detachably connected to and carried by the mouth thereof having a relatively small aperture therethrough and a coupling member formed integrally therewith, a removable lubricant-delivery member arranged in abutting relation to the lubricant-receiving member also having a relatively small aperture registering with the aperture in the cover and a complementary coupling mem-' ber integral therewith cooperating with the coupling member on the cover to bind the two members together, and a tapered nipple and seat engagement'between the two members surrounding the apertures thereof to seal the joint therebetween'when the cou- 1 pling members are engaged.

In testimony whereof I afiix my slgnarture,

inpresence of two witnesses. I
